20501517 divided by 821 
We want to figure out the number of times 20501517 can be divided by 821.

Advancing to step 1:
If we divide 2 by 821, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 821

Let's proceed to step 2:
20 divided by 821 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Append the next digit (5) from the dividend to 20 and continue with: 205 / 821

Going ahead to step 3:
The number 821 fits into 205 0 times, leaving a remainder of 205.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 205 to get 205.
Take the next digit (0) from the dividend and append it to 205, then repeat: 2050 / 821

Advancing to step 4:
821 goes into 2050 2 times with a remainder of 408.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1642 from 2050 leaves us with 408.
Bring next digit (1) of the dividend behind the 408 and repeat the process: 4081 / 821

Moving on to step 5:
The number 821 fits into 4081 4 times, leaving a remainder of 797.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Subtract 3284 from 4081 to get 797.
Take the next digit (5) from the dividend and append it to 797, then repeat: 7975 / 821

Going ahead to step 6:
When dividing 7975 by 821, we get 9 with a remainder of 586.
The next digit of our result is 9. 
Result so far: 249.0
Deduct 7389 from 7975 and we're left with 586.
Append the next digit (1) from the dividend to 586 and continue with: 5861 / 821

Advancing to step 7:
If we divide 5861 by 821, we get 7 and a remainder of 114.
Use 7 as the next digit of our solution. 
Result so far: 2497.0
Subtracting 5747 from 5861 leaves us with 114.
Append the next digit (7) from the dividend to 114 and continue with: 1147 / 821

Let's proceed to step 8:
821 can be fit into 1147 1 times, resulting in a remainder of 326.
Put 1 as the next digit of the answer. 
Result so far: 24971.0
If we subtract 821 from 1147, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Advancing to step 9:
If we divide 3260 by 821, we get 3 and a remainder of 797.
The next digit of our result is 3. 
Result so far: 24971.3
The remainder is 797 after subtracting 2463 from 3260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Step 10:
If we divide 7970 by 821, we get 9 and a remainder of 581.
The number 9 becomes the next digit in our result. 
Result so far: 24971.39
The remainder is 581 after subtracting 7389 from 7970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5810, and continue the process.

Going ahead to step 11:
821 goes into 5810 7 times with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 24971.397
If we subtract 5747 from 5810, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Advancing to step 12:
821 can be fit into 630 0 times, resulting in a remainder of 630.
Write down 0 as next digit of the result. 
Result so far: 24971.397
If we subtract 0 from 630, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Going ahead to step 13:
When dividing 6300 by 821, we get 7 with a remainder of 553.
Record the quotient 7 as the next digit in the result. 
Result so far: 24971.39707
If we take 5747 away from 6300, we end up with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Going ahead to step 14:
821 goes into 5530 6 times with a remainder of 604.
Write down 6 as next digit of the result. 
Result so far: 24971.397076
If we take 4926 away from 5530, we end up with 604.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Going ahead to step 15:
When dividing 6040 by 821, we get 7 with a remainder of 293.
Put 7 as the next digit of the answer. 
Result so far: 24971.3970767
The remainder is 293 after subtracting 5747 from 6040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 16:
821 can be fit into 2930 3 times, resulting in a remainder of 467.
Use 3 as the next digit of our solution. 
Result so far: 24971.39707673
Subtracting 2463 from 2930 leaves us with 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

The final result is 24971.39707673 with a remainder of 4.67e-07.
